Method for predicting call quality and call quality prediction service apparatus for performing the same

Abstract

Disclosed herein is a method for predicting a call quality with respect to the other side by one side of the first and second Internet communication apparatuses, the method comprising: performing a transmission test for predicting call quality between one side and other side through address information of the one side or address information of the other side; and sequentially completing a call quality prediction regarding a relay section formed between the first and second Internet communication apparatuses and mutually adjacent call quality prediction apparatuses in at least one media relay apparatus when there is at least one media relay apparatus that performs media relay among the relay apparatuses between the first and second internet communication apparatuses.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part application, and claims the benefit under 35 U.S.C. §§ 120 and 365 of PCT Application No. PCT / KR2017 / 000839, filed on Jan. 24, 2017, which is hereby incorporated by reference. PCT / KR2017 / 000839 also claimed priorities from Korean Patent Application No. 10-2016-0008727 filed on Jan. 25, 2016, Korean Patent Application No. 10-2016-0173727 filed on Dec. 19, 2016, and Korean Patent Application No. 10-2017-0011333 filed on Jan. 24, 2017, which are hereby incorporated by reference.BACKGROUNDField[0002]The present invention relates to a technology of predicting call quality, and more particularly, to a method for predicting call quality and a call quality prediction service apparatus for performing the method, which can predict call quality through a transmission test using an SIP transaction request and an SIP transaction response without a process of generating an actual call between Internet communic...

AI Technical Summary

Benefits of technology

The disclosed technology allows for predicting call quality and provides opportunities to take other measures before the call is connected. It also avoids unnecessary prediction tasks and prevents overlapping between call quality predictions. The method includes measuring the call quality in a waiting state and predicting the call quality for each section before the actual call connection. Additionally, the technology can generate and calculate media traffic to prepare for possible packet damage in wireless sections. Overall, the disclosed technology improves call quality prediction and enhances network operation efficiency.

Problems solved by technology

The Internet phones using a typical SIP protocol have a limitation in that the call quality may be deteriorated by the overload of a terminal compared to a circuit switching type of telephone in which the actual bandwidth is physically guaranteed or by the system and network congestion state of the intermediate nodes such as L2, L3 and L4 switches in a packet switching network.
